Abstract

In a process and an apparatus for the biological purification of water with the aid of a closed trickling filter which is operated with pure oxygen and/or air, and with a downstream upwards filter with floating matter and intermittent flushing, the saturation of the gas blanket which mainly contains oxygen in the pressure trickling filter is controlled by choosing the operating pressure so that the oxygen supply on the one hand corresponds to the biochemical oxygen demand of the water, and the on the other hand a residual oxygen content dissolved in the water makes continuation of a biological final purification in the upwards filter possible, and thus replaces conventional final clarification. <IMAGE>
